ivo. 846,600,

To all w/tovmfit mag/concern.: i

- ofthe United States, residing at Detroit, vin

the' county ofk Wayne andvStatc of Michigan, have invented newand useful improvements in Water-Closet Bonds, of which the following is a speciiication. Y f1 1 My invention relates to plumbing, and has lparticular reference to water-closets. bends which make theconnection with and carry the soil from-the closet to the soil-pipe stack,

and is so constructed that it provides for the discharge of. the waste from the bath-tub,

lavatory, sink, or other. iixtures into the soilpipe stack either with a Y or T connection without danger of siphoning, as hereinafter set forth. Y

A further object of niy invention is to provide a water-closet bend constructed in such a manner that it provides fon carrying the waste from lavatories, bath-tubs, sinks, and

the like into the soil-pipe stack and which bend shall be as substantial and sanitary as possible and at the saine time be readily adapted to various circumstances and conditions. lleretofore thescbends have been constructed of lead, two forms being inl c'om-A inon use, one the combination iron feri'ule and lead bend and the other one having-a brass iferrule the saine size as the lead bend and connected. thereto with av wiped joint. `ln both` of these constructions the waste connections are run into the. lead bend and joined thereto with a soldered joint. These forms of construction frequently cause trouble, as the lead bends are liable to eraek under the wiped joints and aronrd the bottom of the lead bend, causing a leak. These Acracks and leaks may be from several causes, such as the settling of the soll-pipe stack or of the building orby expansion and contrae `tion of the bend, both hot and cold water being discharged into them. .The work Vnecessary in making these forms of emrstruction has a` tendency to weaken the lead by overheating. y

With these and other objects in view my invention consists generally of a co|nbination \\'ate' 1closet 'bend with flange arranged toreceive soil and waste Vfrom water-closets, bath-tubs, lavatories, sinks, or other lixtures and to carry said waste direct to the soilpipe stack with only one calked or screwed joInt without danger of siphon action one upon the other, and .is also constructed that the floor connection can be scre'wedin .at any Specification of Letters Patent.

tinIe. beforethe Hoor is laid, thus avoiding danger of injury by Plasterers and other workmen before thel ioor is laid.

My invention further consists in the nove details of construction and in the peculiar arrangement and relative` positions of the several parts, all as hereinafterdescribed and particularly pointed out.

My invention will be more readily understood by reference to the drawings hereto attached, in which- Figure 1 is a view in perspective showing my invention with the partsunited. Fig. 2 is a sectional view. of Fig. 1. Fig. 3 is a sectional view of thefenlarged` end of my bend. Fig. 4 is an end view of the enlarged end. Fig. 5 is a sectional view of the bend, showiner how the lead ipe is connected without a soldered joint. 1g. 6 shows the form of flange usedin Fie. 5. -.Fig. 7 is a sectional view of Fig. 8, which gure shows the eccentric forni ofthe flange 'of my bend.

Similar letters refer to similar parts throughout the several views.

A is the water-closet bend and 'i's preferably made of cast-iron of the same general vstyle as to thickness and quality of iron used as ordinary cast-iron soil-pipe. This bend is provided with thc Waste-opening E, the said opening being threaded to receive the pi making connection for waste from otherV tures than the Water-closet. It will be no ticed `that the opening E is made on the top line of the bend, and as the opening of the closet is of less capacity than that of the bend there will always be` an air-space at the top thereof, and the connections beingmade at the top siphoning will thus be prevented. An opening, preferably two nchesin diameter, may be provided in the top of the bend for vent of closet whcreversuch construction is requiredor desirable. The inlet end of the bend A is constructed. with the heavybead a, thus providing for additional strength 'at this point. This bead a. is threaded on the. inside to receive the brass langc B,' Whichv is also threaded. The outlet end ofthe bend isintended to enter a T or Y in the soil-pipe stack with a calkcd or screwed connection' in the usual manner. i i

The brass ila-nge B, the construction of which can be varied and used in the form of a collar-or thinible, has the threaded extension i b, as shown in Fig. 2, for the purpose of4 making, a screw-joint connection wlth the inletV roo -c'old'i'vater passes the lead pipe C.

gether with red orvvhite'leadto make a tight joint Without the"'use' of a Washer. To the upper side of the brass flange B is attached the lead' pipe C, which may be of any re uired length to extend far enough above the oor to make the usual opening for the closet. The leady pipe is connected to the flange B by means ofthe soldered joint D, Which may be the flange and then turned over the extension b 'oi the flange and up the side thereof, the said extension t in ,this construction being only about one-half threaded, 'the plainpart thereof being somewhat reduced in diameter to -form al recess d, into which the lead pipe C is fitted. The flange and lead pipe thus arranged are screwed into the bend A until the the bend, which is lowered into the opening,

tionv 'of the 'closet-opening .lea

comes in contact with and is screwed tightly against the shoulder e at the neck of as shown in the drawings, to more eiectively provide'an air-space at the top of the bend, the sides of the bendbein enlarged at this point in order to maintain the full capacity of4 the bend, asis shown by H in Fig. 8. The lead is caught by the screw-thread of the bend, -as is s own in Fig. 5, 'and with the-use of 'v'vhite or red lead ra tight permanent joint is lassured.l

Inboth forms of construction the flange is provided with the lugs c to assist in conveniently screwing the parte tightly together.

' Figs 7 and 8 vshow a variation of myinvention, which allows of the shitting cf the 'posi- Tbis is accomplished by constructing the ii'ange C with the opening at one' side of the center, whereby ari-eccentric i's formed, and increasing the size ofthe inlet end ofthe bend to correspond 'With y the increased size of the flange so as to rec'eve the same.

The ositien of the lead pipe can bevarie'd 'to any. esi'r'ed point within t e vradine 'cf 'the eccentric.

The flange B .and 'ehe'leed pipe'ocefl be united With a soldered joint Inadea't the lower .end of the extension b 'of the iange Whenever 'such sirable.v 'j l The enlarged end oi the bend is shown in Figs. 3 and 4. This 'construction' rovides construe'tion4 would bedes for one for 'more Waste connections ot er, than from the closet and'is constructed. in such a' manner that with one oalked joint or screwed connection of the vbend with the 'soil-pipe a Wped o`r sweated joint or of any/approved.

threaded to receive a flangel l ing an opening eccentric tothe threaded porstack tWo or more openings for Waste are provided for and the Waste conducted tothe soil-pipe stack Without danger of Siphon action on the Waste connections from the discharge of soil through the bend, as waste connections are run along the top or side of the outlet end ofthe bend, and ybythe use of l the partitions G each Waste-opening has direct and separate communication to the soilpipe stack at 'all times. By making the proper and necessary connections with they chambers G this construction can also be used for vent purposes. While I prefer the construction, as shown in the drawings, having the partitions G,`still these artitions may be omitted, and the waste a lowed to dis*- charge into the .bend at the to line before enteringthe soil-pipe stack an yet be protected from siphon action, as hereinbefore set forth. While in the drawings I have only shown the' construction last described with an enlarged end, I. Wish it understood that the same general arrangement and con struction may be used With a bend having the outlet end contracted but allowing suffi Ycient capacit in the bend to take care ofthe Waste from t e closet.

.The bend can alsobe 'made with the T connectionof thesoil-pi'pe stack and the bend cast together in one piece,with a vent-o ening in the top and near the outlet end o 'the bend. 4By reducing the length `of the outlet end of the bend 'and providing it with standard screw-threads and other slight changes my im roved bend can readily'be adapted to be use in'whatis-klown among plumbers as the "Durham system.

I Wish` it understood inlet connections into the bend can be mede by use of a hub to receivel 'a ferrule 'and calked joint, in the place of screw connections, 'as herein shown and described..

Modifications of the miner details of my improved soil-'pipe bend f 'will doubtless readily suggest themselves tio those s kiiied in thev a'rt to which it appertains, andv I therefore do not desire to limit myself tothe exact details of construction herein shown and 'described. j.
